The parameters on this tab enable you to define a falloff for the field so that the strength of the force will increase gradually towards the centre of the field as opposed to uniform force strength throughout the field.
A falloff enables a smoother interaction with objects because the force will increase gradually rather than abruptly as the objects move into the field.
Choose the type of falloff: None (the default), Linear, Inv. (Inverse), Inv. Square, Inv. Cubic or Step.
The Inner Distance and Outer Distance values determine the start and end distances respectively from the origin over which there will be a falloff of the force.
The Inner Distance and Outer Distance define the volume in which the falloff of force will happen.
The example above shows a spherical field with an Inner Distance and Outer Distance defined. Within the Inner Distance, the full strength of the force will be exerted.
The following falloff options are available:

With Step there will be an abrupt transition from no force to maximum force.
Entry field for Inner Distance value.
Entry field for Outer Distance value.
When an object is between the Inner Distance and Outer Distance, the strength of the force exerted on the object will falloff according to the function defined under Falloff. When an object is outside the Outer Distance, the field will exert no force on the object.
You can define the Outer Distance to be larger than the field itself. However, an object will experience a force only when it is inside the field’s shape.
